Sasha (Augusto) Kielbowicz
Scientific Software Architect & Research Engineer
I architect production-grade AI systems and high-performance engines for Quantitative Finance and Scientific Computing. I translate heavy computational models and agentic workflows into fault-tolerant, 3x faster systems using Julia, C#, and Stochastic AI, with a focus on rigorous evaluation and large-scale integration.
What I Do
Research Software Engineering (RSE)
I translate scientific research into industrial-grade software engineering through Phorma, a consultancy I co-founded with Agustín Corbat. We help R&D, BioImage, and Quantitative Finance teams build stable and reproducible systems.
Mission: We handle the engineering so scientists can focus on discovery. Read more about why I created Phorma.
High-Performance Computing (HPC) Sprints
Your Python models are too slow. I optimize numerical bottlenecks using Vectorization, Caching, and Parallelism.
Proven results: 300% performance gains at Axioma/Qontigo, enabling real-time risk calculations in production.
Deterministic AI Architecture
Integration of Neural Stochastic Differential Equations (NeuralSDEs), Agentic Orchestration, and Math-Aware RAG systems. I build the “guardrails” and evaluation frameworks that allow Large Language Models to handle financial and scientific data without hallucination.
Key work: Implementation of agentic workflows using Model Context Protocol (MCP) and research into NeuralSDEs using Julia for superior convergence.
Domain-Specific Language (DSL) Design
I design custom languages that allow Quants to define complex pricing models safely and intuitively, abstracting away the code complexity.
Outcome: Enable non-engineers to construct and test pricing logic without exposing underlying complexity.
